ELF hello world not being decompiled on ubuntu 20.04

[dnns92]

OS: Ubuntu 20.04 LTS

Boomerang version or git hash: version: boomerang-cli v0.5.2-366-g1944b804e

Steps to reproduce:

1. write hello_world.c and use gcc hello_world.c -> a.out file
2. $ boomerang-cli a.out

Expected behaviour/output: decompilation

Actual behaviour/output: input error: unknown binary file format (see below)

Additional comments: I tried to load it via the boomerang-gui, but I got the same error. The file is an ELF file format (so it should be supported), see output of "file a.out": (base) nano@nano-laptop:~/repos/cpp$ file a.out a.out: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=cd65f2417054c4964ea4e36cf80c5961f9a346f2, for GNU/Linux 3.2.0, not stripped

Boomerang does not yet support decompiling 64 bit executables; see also #49. Decompiling simple 32 bit executables created with gcc -m32 should work.
